WINDOW VENTILATDR.

Application filed October 30, 192%. Serial No. 597,990.

vented a certain new and useful lWindow' Ventilator, of which the following` is a specification. y

This `invention relates to window ventila tors of the type wherein a deflector is located upon the window sill, at the inner side of the room, opposite to the lower window sash, and the latter is partially opened; whereby the air enters and strikes the deflector, which directs it upwardly, and the incoming current is in this manner spread over the entire room gradually and evenly, and also uniformly, without causing any draft which .is injurious tothe occupants.' n

The principal object of my .invention is to provide an improved ventilator of this type, which is simple, inexpensive, conveniently and economically manufaeturable, convenient and economical of installa-tion by the user without requiring` any skill, conveniently utilizable, strong, rigid and durable, and which when in use may be readily and conveniently detached entirely 'from its place by the user, and reattaehed by him when it is desired to return it to its operative` position.

Another object of the invention is to provide a ventilator of this type, which is entirely nuinufacturable and capable of be ing; fitted to any width of window, without requiring any spceial work or any kind of reconstruetion ot any part thereof.

Other objects and advantages will hereinafter appear. y l

rl`he inventionherein is an improvement upon the window'. ventilator shown and described in my copending` patent application, tiled April let, 19.21, Serial No. 461,197.

In the accompanying` drawings,-

Fig. 1 is a general perspective view sho\v ingfa ventilator embodying` those improvements.

Fig. 2 shows a front elevation of the which is mounted a deflector l.V Said de-` fiector comprisesa glass pane 5, and akpair ofmetallic frames 6, 7, theformer of which telescopes into the latter, as shown, in Fig` hthe web 6 of frame G slipping into the web 7' of frame 7. Each of the frames 6, 7 is provided with a sunken flanged portion 8 which bears against the pane 5. The frames 6, 7 are secured to each other by means of bolts 9 passing through the frame G and headed nuts 10 passing` through the frame T and threading over the bolts 9. Upon fastening the bolts 9 and nuts 10 to each other the flanges 8 are caused to rmly grip the pane and hold it in secured position,

the springiness of the metal at the bentpor# tions llof' the frames 6, 7 aeting to `make the said bolt resilient upon the glass pane, so as to .protect thelatter against breakage during,` handling, `while affording the firm grip upon the pane.

`The detiectors t are preferably manufactured in units of 251-, 30, 36, 4.-2,fetc.,`

to fit widths of windows of standard `dimensions. When it is desired to tit windows of uneven or non-standard widths, such `as 25, 27, 39, etc., the following means is resorted to. Over each end 12 of the defiector is slipped an extension-member 13, which is channel-shaped in Cross-sectional configuration, as shown in Fig. t, and is made from the blank sheet-metal member shown` in Fig. ln assembling the deflector d with the extension-members 13, the,

blank, Fig. 5, is bent along the places indicated bythe dash and dotted lines lil to form theohanneh and slots 15 formed in said blank are `thereby brought into registry with the bolts 9 and nuts 10. The belts and nuts 9, 10 are then .passed through the slots 15 and the frame-parts G, 7, the members 13 are .slid outwardly to extend the length of the detlector to the width of the window to be fitted, and the bolts and nuts 9, 10 are then tightened together, whereby the frame parts 6, 7 and the members 13 are permanently secured together in vthe adjusted position. The sliding stroke of each of the members 13, relative to the deflector proper, is 21/2 inches, by which means the deflector may be extended from one inch to a maximum of five inehes beyond the length of the deflector proper, so as to it' to windows of any width between those of the standard dimensions above mentioned. 1n

assembling the members 13a pair of strips 16 thereofat the upper ends of the members are bent over, as shown at 17 Fig. 3, to add strength to the members, and provide a neater ap earance of the structure at thisl place. T e edges 18 of the members 13 are bevelled oli toward the pane 5 to forni al flange thereat which serves to close the space between the walls 19- of the members 4and the ane.

The brackets 3 may be constructed in any suitable manner and preferably in the mannershown and described in my above inentioned pending application. Said brackets are provided with stri-psy 20 having openings 251, and the members 13 are provided with stamped out projecting portions 22. When it is desired to mou-nt the deflector l in operative position uponthe window, the pro,- jecting por-tions 22 are inserted into the openings- 21, and thedefleetor is permitted td drop downwardly, whereupon the circular portions 23 of' the stamped portions 22 pass` through the circular lportion-s 24- et open-ings 21 and become positioned beyond the narrow parts 25 of said @pen-ings, and in this manner lock the det-lector to the stri-ps 20ctv the brackets 3.

Vari-ations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
